"""Pool scheduling hooks -- provider-type-specific pool behaviour.
|
|
|
|
Some provider types need custom logic during pool scheduling (e.g. extracting
|
|
a session UUID for sticky binding). This module provides a small Protocol +
|
|
registry so the pool layer stays generic while provider-specific behaviour
|
|
lives alongside each adapter.
